Nonrn n. Losny, or AKRON, oHIo SUCTIN CLEANER Application led April 20,

This invention relates to suction cleaners. The general purpose of the invention is to provide in the suction inlet of the usualvnozx zle of a vacuum cleaner a combined brushing and beating element by which a continuous brushing action .is mainta'ned, coupled withv periodic beating or shaking action on a door c radius than other areas to impart a beatingl a' or shaking as well as 4a brushing action on the door coverings.

y The foregoing and other objects are obtained by the devices illustrated in the accompanying drawing and'- described below, it being understood that the invention is not limited to the particular forms herein shown and described.

Y Referring to the drawing, the numeral 10 .5, 'designates' the usual nozzle of a motor-operated suction sweeper. Journaled in the nozi l zle so as to operate' in the inlet ll'thereof is a combined brush and beater 12 which may be driven in any suitable manner, 'for exo ample, by the central drive shown, includingvl ,brush 25 is rotatably mounted on a rotoi` 26 1927.

a belt 13 trained over a central pulley 14 on lbrush 12. Belt 13 may be driven from a shaft 15 by a pulley 16, shaft 15 being driven by the rotor of the suction fan (not shown).

The brush 12 herein shown may be constructed in two sect-ions 12a and l2b of twisted wire core brushes, the outer ends of which are journaled in the nozzle in any suitable way and the inner ends of which maybe directly connected to pulley 14, but in the form shown in Figure 1 are connected to a member 20 journaled in pulley 14 so as to be capable of rotating with respect thereto. Member may include sections of vulcanized rubber 2()a and 20b in which the inner ends of brushes 12l and 1,2b have been embedded the sections 20a-and .2()b being cemented or vulcanized together.

Each section 12n and 12b ofthe brush is shownwith longer bristles as at 21, 21 on one To side than on the other so that the periphery of the brush is eccentric with respect to the core thereof (Figure The eccentricity is preferably in opposite directions on opposite sides of the center of the element, as shown, and adjacent the 'ends the bristles are cut away as at 22, 22 to prevent marking of a floor covering.

In the forms shown in Figures 4 and 5, the

so that it will rotate relatively thereto as it hits the floor covering 'and the eccentricity of the brush periphery gradually changes from one end of the brush to the other, being substantially concentric with the brush airis at 85 the center. This provides, in addition to the beating action alternately on opposite sides of the'center, a longitudinal oscillatory movement of the brush periphery which shakes or vibrates the floor covering transversely of the vul line of travel of the cleaner.

In the form shown in Figures G and 7 the .brush rotatable on rotor 31 is formed with raised patches 32 of bristles which may' be arranged in helical or other formation to hit 95 aoor covering in. succession in any desired order.

The form f brush 35 shown in Figures 8 and 9 is rotatable on rotor 36 and has'thereon a raised helical contmuoua rib of' bristles .'-100 adapted to impart a beating action to a iloor covering and also a lateral or transverse shaking action thereto.

In all forms of the invention the raised 6 bristlesserve tov beat and shake a floor covering with a positive, yet not too strenuous, action thereon, in `the preferred forms the brushes slipping or rotating as they hit and the bristles also yielding as Will be under- 10 stood. t I

Modifications of the invention may be resorted to Without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

l. A suction cleaner having a suction nozzle provided With an inlet, a rotor above the inlet, a brush rotatably mounted on the rotor so as to be operable in the inlet, the only axis of rotation of the brush being coincident with the axis ofthe rotor, said brush having a. pair of equal sections, the peripheries of said sections being'oppositely eccentric to the axis of the rotor, and means for driving said rotor. v. 2. A suction cleaner having a suction noz'- zle provided with an inlet, a rotor above the inlet, a brush rotatably mounted on the rot-or, soas to be operable in the inlet and having its only axis of rotation coaxial with said rotor, said brush having sections, the peripheries of said sections being oppositely eccentric to the axis ofthe rotor, and means for driving said rotor. y

3. A suction cleaner having a suction noz-` zle provided with aninlet, a rotor above the' inlet, a brush rotatably mounted on the rotor so as to be operable in the inlet and having its only axis of rotation coaxial with said rotor, said brush having its periphery eccentric to the axis of the rotor, and means for 40 driving said rotor. l

4. A suction cleaner having a suction nozzle provided'with an inlet, a rotor in said nozzlev above the inlet, a brush .rotatably `mounted on the rotor, the axis of rotation of the brush being coincidentvvith the rotor axis and-horizontally disposed so as to be parallel to a oor covering, said brush having portions -of its periphery extended farther from said brush axis than other portions to impart a beating action to a floor covering, and means for driving said rotor. l

5. A suction cleaner having a suction nozlzle provided with an inlet, a rotor in said nozlzle above the inlet, a brush mounted on the rotor, the axis of rotation of the brush being coincident with the rotor axis and horizontally disposed so as to be parallel to la floor covering, said .brush having ort'ions of its periphery extended farther rom said axis than other portions to impart a beating acy tion to a iioor covering, and means for driving said rotor. f
